● Report designer · viewer · engine
An MIT-licensed report designer, viewer and engine. It streams a million rows in about 320 MB. See the benchmarks →
exportPdfStream in Node: about 260 MB peak from 20,000 to 100,000 rows (measured).rdl / .rdlc, ActiveReportsJS .rdlx-json, JasperReports .jrxml, BIRT .rptdesign (try your own file)01
Real report definitions from the repository, rendered by the embedded viewer. Page through them, change parameters, drill in, export. The ones marked designer-built were made in the designer with no code.
The viewer loads when you get here.
02
The stress report: a grouped table with a sparkline and a data bar on every row. Pick a size; the rows are downloaded as JSON and laid out right here, on the page's main thread.

The 1.6 s figure in the spec sheet is the engine in Node on a laptop. Your browser number depends on your device; nothing here is cached or precomputed.
Pick a row count to start.
03
The full designer, mounted with mountDesigner(). Drag items from the toolbox, edit expressions, switch to Preview. Save keeps your edits in this tab; nothing is uploaded.
The designer loads when you get here.

The viewer and designer are one script or ES module. Thin wrappers for four frameworks (the framework is a peer dependency; nothing is bundled twice). Both packages are on npm: @reportwright/engine makes PDFs in Node, @reportwright/viewer runs in the browser.
npm i @reportwright/engine @reportwright/viewer

From the project's status document. Everything listed runs and is covered by tests; the right-hand column is what it does not do yet.
Page bands, multi-column body, keep-together and keep-with-next, page breaks between groups, table of contents with final page numbers, galley (pageless) view. Pure JavaScript with no DOM, so the same code renders in the browser and in Node.
JSON, CSV, REST, GraphQL, and SQL run on the server (SQLite, Postgres, MySQL). A response explorer finds the rows in an API response. Filters, sorts, lookups, nested data sets, report functions.
Parameters with sliders, ranges, date ranges, cascading lists and options from data. Collapsible groups whose totals and paging stay correct, click-to-sort headers, drill-through with a breadcrumb, document map, search.
Column, bar, line, area, pie, donut, scatter, bubble, radar, polar, candlestick, OHLC, gauge and funnel. Combo charts with a second axis, 100% stacked and range series, log axes, trend lines, moving averages, reference lines and bands, data-label templates, 12 palettes or your own colours.
Pivot tables with nested row and column groups, totals, % of total, row or column, and expand and collapse. Merged cells, recursive groups, body sections, tables wider than the page, items inside cells. Sparkline, data bar and bullet in cells; 49 barcode symbologies as vectors; rich text.
Master reports with a content placeholder (masters can have masters). Report part libraries, inserted linked or as a copy, with typed properties. Themes chosen at run time, named styles, and layers for screen, print, export or the designer only.
Imports SSRS / Report Builder .rdl and .rdlc (RDL 2008, 2010, 2016): data sets, parameters, tablix, charts, subreports, actions, VB expressions. Imports ActiveReportsJS .rdlx-json. What changed is listed as notes.
PDF with links and an outline, Excel, Word (real tables), HTML, CSV and JSON (the laid-out pages) from the viewer. On the server: every format by URL, batches, schedules with time zones, signed webhooks, API keys, and a pw CLI that renders and diff-tests reports in CI.
Smart guides, rulers, align and distribute, groups, sort and filter editors, table and matrix gallery, a pivot wizard, instant visuals, chart series and overlay editors, drag a data set to get a table, version history, an expression editor with completion.
Folders and permissions per report and folder for users and groups, enforced on every path. An append-only audit log of sign-ins, views, renders and exports. Single sign-on with OpenID Connect and SAML 2.0, IdP groups mapped to roles. Not part of this static demo.
Viewer UI in English, Hindi, Spanish, French, German, Japanese, Chinese, Portuguese (BR) and Arabic (right-to-left). Report text is shaped with HarfBuzz, with bundled Noto fallbacks for Devanagari, Arabic and Hebrew.
